9 Claims This invention relates to an improvement in spraying devices ofthe character used for the distribution of liquid insecticides or otherliqbeing disclosed in the co-pending application of William MartinVogel, Serial No. 182,156, filed December 28th, 1937.

The present invention has for its object the provision of a built-insprayer of the character described by which the contents of the can maybe sprayed directly from the can; which does not interfere with thenormal use of the can 15 whereby when desired the contents may be pouredout in the conventional manner; which will prevent wastage of the liquidcontents of the can and provide other advantages hereinafter pointedout.

In the accompanying drawing, wherein an embodiment of the invention isshown, Fig. 1 is a sectional view through a combined can and sprayermade in accordance with the invention; Fig. 2 is an enlarged sectionalview through the liquid 25 supply opening in the top of the can, showingthe spout and closure cap; and Fig. 3 is a sectional view on the line 33of Fig. 1, looking in the direction of the arrows.

With reference to the structure shown in Fig. 30 1, the body of a can orsimilar receptacle is shown at l, and the same may be of any suitableform and size convenient to be held in one hand, while the built-insprayer is operated with the other hand. A can of approximately quart 35size has been found convenient. In the form shown, the body of the canis substantially rectangular in cross-sectional shape. Seamed to theupper end of the body I in the conventional manner is the top 2 andsimilarly secured to w the lower end of the body is the bottom 3. Ex-

tending through the body of the can from top to bottom thereof is a tube4. Said tube is normally open at the top and bottom and does notcommunicate with the interior of the can. Fitted Within the tube 4 andextending concentrically therewith is a cylinder 5 forming part of aspraying device, said cylinder being closed at one end by a conicalplug-receptacle or socket 6 secured in the end of the cylinder 5.Recepta- D cle 6 has a portion 1 internally threaded for the receptionof threads B-formed on one end of a conical plug 9 which fits into thereceptacle 6, and which, when unthreaded from the threads within theportion 7, is used as the operating handle of the sprayer. Plug 9 issecured on one 1938, Serial No. 198,162

end of a piston rod I2 movable ture ll formedinthe inner end or wall IUof the conical receptacle 6.

Secured on the other end of the piston rod 12 is a piston ployed inspraying devices, said piston being mounted for reciprocation in thepiston chamber or cylinder 5 by manipulation of the plug or operatinghandle 9, located at the bottom of the can body.

The upper end of the cylinder 5 is closed by a disc-shaped head plate 20which is exposed at the top of the can body and is provided with thecentrally located air spray opening: 2|. Located within the cylinderwith a cupped portion 15 constituting a valve chamber within which adisc valve I! is located. A cap I8closes the valve chamber, said capbeing formed with the opening l9 while the cupped portion 15 is providedwith the opening I6. Through the mechanism thus far described, it willbe apparent that when the plug 9 is unthreaded fromthe receptacle 6and'moved to and from the bottom of the can, piston 13 willcause an airstream to be intermittently issued from the air-spray opening 2 ILocated remotely from the air-spray opening in the top of the can, is aliquid-supply opening 23 communicating with the interior of the can.Surrounding said opening and upstanding from l3v of the'kindconventionallyem- 5 is a partition I 4 formed through the aper- I at thetop of the can.

the top of the can is a cylindrical threaded spout 24. A siphon tube 22attached to the top of the can by soldering or the like has one of itsends located adjacent to the spray opening 2| and has its other endcommunicating with the interior of the spout as indicated at 25.

The spout 24 is intended to receive a closure cap 26. Cap 26 is providedwith a threaded plug portion 29, which, when the sprayer is to bemaintained in inoperative position, is threaded down into the spout bythe closed end of said plug portion will cover the liquid-supply opening23 as well as the end 25 of the sip-hon tube. Thus, communicationbetween the liquid-supply opening 23 and the siphon tube 22 will be shutoil and no liquid can be drawn through the siphon tube 22 should thepiston I3 be reciprocated while the closure cap is in the positionshown, or with the plug portion thereof located in the spout 24.

The closure cap 26 is also provided with a threaded cup-shaped portion2! at its end opposite to that on which the plug portion is located.When it is desired to render the sprayer inoperative, the cup-shapedportion 27 of the 24 as shown in Fig. 1, whereclosure cap is threaded onthe outside of the threads on the spout, as shown in Fig. 2, and saidcup-shaped portion of the cap will then form the spout 24 into a liquidchamber into which liquid from the can may enter and from which it maybe drawn through the siphon tube 22 when the piston I3 is reciprocated.The wall or partition 32 in the cap extends over and closes the end ofthe spout 24 when the cupshaped end of the closure cap is in position onspout 24 and a suitable washer or gasket is interposed between said wallor end of the spout.

It may be desirable to utilize an absorbent material such as felt or thelike in the spout, as shown at 28 in Fig.

said absorbent tending to provide a uniform flow of liquid through thesiphon tube. the felt 28 may be contained or stored in the cup-shapedportion of the cap during the periods when the parts are in non-sprayingposition, or in other words, when the plug portion'29 is inserted withinthe spout. By means of the reversible closure cap shown it will beapparent that the can may be sealed against leakage and evaporation whendesired or placed in condition for spraying by merely reversing theposition of the closure cap upon the spout.

When the can is sold, it is substantially full of the insecticide orother liquid adapted to be sprayed. At that time the closure cap 26 isin its closed position, namely, that wherein the plug portion 29 isthreaded into the spout 24 as shown in Fig. 1. To place the device incondition for spraying merely requires the absorbent 23 to be placed inthe spout 24 and the closure cap to be reversed or placed with itscup-shaped portion threaded on the outside of the threads on the spout.Upon reciprocation of the piston l3, the air blast emitted fromair-spray opening 2| will draw moisture through siphon tube 22 and sprayit in a finely diffused stream.

Various means may be utilized for holding the cylinder 5 within the tube4, such means being arranged to either provide a permanent maintenanceof cylinder 5 in tube 4 or permit the cylinder and associated elementsto be bodily removed when desired. In other words, if desired, thesprayer, composed of cylinder 5 and its contents may be sold separatelyfrom the can and the purchaser, to at once convert the can into aspraying device, need only insert the cylinder into tube 4. These andother modifications may be made without departing from the spirit of theinvention.
